Probe
The control unit and the PTC thermistor probe are connected by
means of a signal cable. The tip of the probe is equipped with a PTC
thermistor. During operation, the PTC thermistor is heated and can
distinguish between gaseous and liquid media due to the different
heat dissipation.

3.1 Operating modes
When the mains voltage is switched on, the connected PTC thermis-
tor heats up. Three different operating modes must be distinguished.
The various operating modes are set by means of a selector on the
printed circuit board.
Operating mode “Probe 1”: level switch
Only the signal received from probe 1 is processed. A second probe
may be connected, but it will not be considered.
If the PTC thermistor is exposed to air (i. e. not submerged in liquid)
once probe 1 is fully heated up, the yellow LED "Probe 1" goes out,
the green LED "Release" lights up and the output relay is energised.
If the PTC thermistor of probe 1 is submerged in liquid or if the heat-
up process of probe 1 is not yet finished or if probe 1 is not con-
nected or short-circuited, the yellow LED "Probe 1" lights up, the
green LED "Release" goes out and the output relay is de-energised.
Operating mode "Filling": level control for filling
Both PTC thermistor probes "Probe 1" and "Probe 2" must be con-
nected. The following applies to both probes in this operating mode:
If the PTC thermistor is exposed to air (not submerged in a liquid)

Product description
8RG 210
once the heat-up process of one probe is completed, the yellow LED
of the corresponding probe goes out. If the PTC thermistor of a
probe is submerged in liquid or if the heat-up process of the probe is
not yet completed or the probe is not connected or short-circuited,
the yellow LED of the corresponding probe lights up.
Logical connection between the two probe signals and an output sig-
nal: If both probes are no longer submerged in the liquid, the green
LED "Release" lights up and the output relay is energised. If both
probes are submerged in the liquid, the green LED "Release" goes
out and the output relay is de-energised.
Operating mode "Emptying": level control for emptying
Both PTC thermistor probes "Probe 1" and "Probe 2" must be con-
nected. The following applies to both probes in this operating mode:
If the PTC thermistor is submerged in the liquid, the yellow LED of
the corresponding probe goes out. If the PTC thermistor of a probe is
exposed to air or if the probe is not connected or short-circuited, the
yellow LED of the corresponding probe lights up.
Logical connection between the two probe signals and an output sig-
nal: If both probes are submerged in the liquid, the green LED "Re-
lease" lights up and the output relay is energised. If both probes are
no longer submerged in the liquid, the green LED "Release" goes out
and the output relay is de-energised.
General information
In case of a power failure, the relay is always de-energised. When
power is available again, both probes must either be exposed to air
or submerged in the liquid before release is possible. A start delay of
approx. 15 seconds prevents a release before the heat-up phase is
completed.
RG 210 can be operated with or without additional external devices.
The following types of additional devices can be used: visual and
audible alarm units, telecommunication devices, building control sys-
tems, building automation systems, pumps, valves, etc.
